E-cigarettes are small, battery-powered devices that usually look like cigarettes. The e-cigarette cartridge is usually filled with propylene glycol, which makes the vapour, and glycerol. Some cartridges also contain flavouring. People may use e-cigarettes to simulate the feeling of smoking without actually smoking tobacco.
Many e-cigarettes also contain nicotine. Different brands and models of e-cigarettes have different amounts of nicotine. When you puff on the e-cigarette and inhale the vapour, the nicotine enters the lungs as a vaporized solution.
The Canadian Cancer Society recognizes the potential benefit that e-cigarettes may provide to Canadians trying to quit smoking, though research in this area is evolving. Other nicotine replacement products are known to help smokers quit and have been approved for use in Canada. E-cigarettes containing nicotine have not been approved by Health Canada for sale and therefore cannot be legally sold anywhere in the country. CCS only recommends nicotine replacement products that have been approved by Health Canada.
Researchers are still looking at how effective e-cigarettes with nicotine can be in helping someone quit smoking. Some studies have shown that e-cigarettes with nicotine may help users quit smoking.
E-cigarettes that don’t contain nicotine can be legally sold in Canada. However, researchers haven’t shown that they are effective in helping people quit smoking. A few studies have shown that there may be low levels of harmful substances in some e-cigarettes, even if they don’t have nicotine.
